What is considered the supreme law of the land?

The Constitution is considered the supreme law of the land because it establishes the framework for the government of the United States and serves as the highest legal authority. All laws, both federal and state, must be in accordance with the Constitution. It outlines the structure of government, the powers of the various branches, and the rights of citizens. This principle is reinforced through the Supremacy Clause, which states that federal law takes precedence over state law when there is a conflict. While the Declaration of Independence articulates foundational ideas about rights and government, it does not serve as a governing document. The Bill of Rights comprises the first ten amendments to the Constitution and protects individual freedoms but is not a standalone governing document either. State constitutions operate within their respective states but must also align with the U.S. Constitution, further illustrating its status as the supreme law.
